Merrifield was always going to cost Stott and Marsh some at bats. I'll give the manager a pass on this as I do think it is good to get everyone on the roster a start during the first few games. I imagine Stubbs will play one game the next series against a RHP.
As for Marsh, I do think they need to give him more responsibility in the lineup. Yes his stats last year were helped by a huge BABIP and a lack of starts against tough lefties, but he also hit very well and is young enough where he can improve some. I am more hopeful for Marsh hitting a higher level than Bohm for instance. I just don't think Bohm will ever be the power threat he needs to be in order to offset the defense. He is fine when his contract is below $10 million (maybe 1 more year of that) but after that I really am hopeful Miller is ready to take over in 2026 or 2027.
Also, let's hope Bryce's hand did not swell up after yesterday. It is nice to get Sosa a game, but hopefully Bryce is available to pinch hit. I'd rather sit Schwarber against a tough lefty than Bryce in the future.
